Specification of Letters Patent.

Application filed August 23, 1909. Serial No. 514,,114.

To all wliom it may concern:

Be it known that I, LOUIS KLUN, a subject of the Emperor of Austria-Hungary, and resident of loaulding, in the county of Sangamon and State of Illinois, have invented a new and useful Miners Lamp, of which the following is such a full, clear, and will enable others skilled in the art to which it appertains to make and use my said invention.

' The purpose of this invention' is to provide a miners lamp adapted to burn oil and ada ted to burn at the same time, or inde- ,pen ently, as may be desired,'gas generated within the lamp.

With these ends in view, my invention,

consists in the novel features of construction and combinations of parts shown in the annexed'drawing, to which reference is hereby made, and hereinafter particularly described and finally recited in the claims.

.In the drawing similar reference numerals designate like parts in the several views.

Figure l is a side elevation ofthe lamp, as it ap ears when the Wick holder is detached; ig. 2 is a vertical axial section through the lamp showing the wick holder in positioni-n the wick tube, and Fig. 3 is a side elevation of the wick holder detached.

The lampcom rises 21 water and oil reservoir 1 and a car id box 2. The box 2 has a screw threaded member 3 screwing into the screw threaded member 4 of the reservoir 1. The reservoir 1 has a diaphragm 5 provided with a central hole 6 accommodat ing avertical tube 7 fixed in the hole; and a hole 8 communicating between'the interior of the box 2 and the as burner 9. A cover 10 is hinged on and c oses the upper end of the reservoir and may be raised to afford access to the interior of the reservoir. A suit- .able spring catch 11 secures the cover in its closed position. On top of the cover 10 is a blow-ofi' box 12 communicating with the interior of the reservoir through an opening 13 and provided with an air vent 14. The box 12 serves to prevent water escaping from the reservoir, and dropping onto the user. In case of excessive gas pressure within the reservoir which would blow out water through the top thereof, the lifted water will pass through the opening 13 into the box 12 and the top of the box above the opening will prevent the water from escaping from The reservoir 1 has an inclined wick tube 15 such as is cdinmonly used. .A hinged cover 16 is adapted to close the upper end of the wick tube and when closed is secured by a spring-catch 17'. A wick holder 1.8 is adapted to fit in the tube 15, and carries a wick 19 which extends downward into the reservoir 1 when the wick holder is in place in the tube.

The tube 7 has an enlarged cylindrical internally screw-threaded .part 20, an opening or openings 21 admitting water, from the reservoir. into the tube, and a tapered valve seat 22. Thefecd controller, for controlling or entirely shutting off the water supply within the tube 7 comprises a handle 23 for turning the controller part 2.4.- screwing into the part 20; a tapered valve 25 adapted to fit on the seat 22; and a needle 26 fitting loosely in and extending downwardly through the lower part of the tube 7. A compressible washer 28 between the handle 2'3and the part. 20, serves to make a water tight connection between the handle 23 and the part 20 when the valve .is completely closed. A burner 9 is central to a reflector 29 of usualconstruction connected in any suitable manner with the reservoir 1.

It is a fact well known to ex rienced miners that in a good atmosphere .ree from black damp, an 011 light will burn brightly, but in the presence of black damn in small quantities, the light will burn dimly and smoke, and if'there is very much black dam hanc an acetylene light willshine brightly in the presence of black damp. It will be seen therefore, 'that the action of the oil light immediately apprises the user of the lamp of the condition of the alt and he is able to avoid proceeding in an a\" mosphere dangerously contaminated with black damp; but if he has the acetylene light, he will have no such warning of the condition as to the air and may unwita screw-threaded tingly enter an atn'losphere dangerously con-e taminated with the black damp. It is therefore of great practical advantage to the mi 1101' to have a lamp adapted to produce both kinds of light, in order that he may when proceeding in an untried atmosphere, determine the condition of the air as he proceeds and if .he finds it dangerous may not gotoo far; and when he reaches the location of hiS work he may after the air has been tested as described, use the bright acetylene:- light to facilitate the prosecution of his work.

It is well known that the acetylene gas I used in the lamps of this kind is generated by water dripping onto calcium carbid 'in properly controlled quantities. It is also well known .that. oil is lighter than water,

and if both oil and water are contained in E the same vessel, the water will occupy the In case it is desired to use both oil and water; calciuiuearbid in suitable quantity will be placed in the boii2 and the box will be screwed onto the reservoir 1; water will then be poured into the reservoir until it reaches the level of the lower end of the,

wick tube; oil will then be poured into the reservoir on top of the Water uutll 1t attains a level a little above the opening of the lower end of the wick tube; the wick having been previously placed in the holder 18, the

holder'will be inserted in the wick tube and the lower end of the wick will be immersed in the oil and the outer end of the wick will then be trimmed and lighted in the usual manner. In proceeding under ground tohis work, the ininerwill use the oil burner and when he arrives at his place of work, if the atmosphere is satisfactory,

he may extinguish the oil burner and ignite and-use the gas burner; or if conditions are unfavorable to the use of the gas light, he

may contin'he to use the oillight. If the conditions are such that the miner uses the gas light he WilI control that light by turning the handle 23 to adjustthe valve to control the How of Water through the port 21 onto the dropping needle 26.

If oil alone is used,- the handle 23 Will be turned to completely close the valve 25 and in that case the lower end of the handle bearing on the. Washer28 Will compress the washer and tightly close the upper end of the part-20;- the reservoir will be supplied with oil and theQoil burner will be used in the manner already described. l

Having fully described my invention what I claim as new and desire to secure by Letters Patent is: 1i

1. In a miners'lamp, the combination of a reservoir adapted to containoil and water, a carbid box connected with said reservoir, a controller adapted to drip water in controllable quantities within the interior of' said carbid box, a wick tube communicating with said reservoir, a wick in said wick tube in contact with the oil in said reservoir, and a gasburner communicating with the interior of said 'carbid box.

'2. In a miners lamp the combination of a carbid box, a reservoir, a tube intercomnuuiicating between saidrescrvoir and carbid box, acontrollcr adjustable to'control the opening and closing of said tube, a wick tube communicating with said reservoir a cover connected with said wick tube, a catch for securing cover, a cover connected with said. reservoir and a catch adapted to secure said last named cover. I

In witness whereof, I have hereunto signed my name at Riverton, Ills, this 10th day of August, .1909.
